Our take on the AKG K 451

by Dave Bar

Travel in style with these compact, high-quality headphones

folding design

A compact, folding design makes the K 451s easy to take along everywhere.

Take AKG's compact K 451 portable headphones with you everywhere to enjoy your music to the fullest, and manage your phone calls with hands-free ease. They deliver the top-to-bottom clarity and accuracy that music lovers demand. Soft, comfortable ear pads team up with the K451's closed-back, lightweight design to block out most ambient noise for undistracted listening. An innovative folding mechanism allows these 'phones to collapse down to a super-compact size for easy carrying inside the included protective case.

in-line mic

The in-line microphone and remote let you easily answer calls on your iPhone and adjust the volume.

Switch between calls and music on your iPhone®

iPhone users get extra-convenient operation. An in-line microphone and remote let you make and receive calls, as well as control basic music playback without even touching your phone. And these headphones are compatible with your iPod® or iPad®, too. Plus, AKG includes two detachable cords — one with the in-line remote/microphone, and a standard headphone cable. Each is designed to be tangle-resistant for fewer hassles on the go.

    not worth the inline controls

    Written By apm_philly, Philadelphia on Saturday, December 15, 2012
     
    I purchased the ak451s because they advertised high audio quality and an inline mic and remote. however, the audio quality while using the supplied in line mic cord was HORRIBLE! I was glad they supplied a regular cord too witch made the sound bearable. Build quality low=very plastic feeling but you get what you pay for there.
    Pros:
    cheap for the audio quality once you get rid of inline mic cord. Also cube filling sound when the office is empty on a saturday and full volume on my phone.
    Cons:
    NOT WORTH THE INLINE MIC!! Go with the graedos (maybe) didn't test them

    Great sound but limited sizing

    Written By DallasListener, Dallas, TX on Tuesday, October 16, 2012
    Crutchfield Customer Review (What's this?)
     
    Sound is wonderful, but the headband does not extend far enough to allow the cups to fit squarely over my ears in daily use. Like most on-ear designs, a good fit is essential both for isolation and for sound quality. So I had to return these because my head seemed a little too big. I'm surprised and very disappointed.

    Fantastic

    Written By BBS, Raleigh NC on Tuesday, September 25, 2012
    Crutchfield Customer Review (What's this?)
     
    These headphones are simply exceptional. I compare the sound output of any audio equipment to the range and detail of my reference quality equipment, and was blown away by the performance of these headphones, particularly given their size and portable application. Sound is a personal preference, but these are worth a try - you too may be pleasantly surprised, both by the great sound quality and the reasonable price.
    Pros:
    Balanced Sound Warm output with clear and deep bass Excellent high level detail Broad music range (even with poor portable amplification) Good build quality
    Cons:
    Size of the band may not fit very big heads
